I have been asked this question by my college director while I was bunking the class.

Question is from Electronic Scanned Array Radar in chapter Surveillance Systems, Mapping and Multimode Radars of Avionics

Answer 1

Right option is (b) 1000 to 2000

To explain I would say: A typical airborne active array contains 1000 to 2000 transmitting modules, each capable of transmitting 5 to 20 watts of power.
